Danmctree··on Python performance myths and fairy tales
The frustrating thing is that the math and AI support in the python ecosystem is arguably the best. These happen to also be topics where performance is critical and where you want things to be tight.

c++ has great support too but often isn't usable in communities involving researchers and juniors because it's too hard for them. Startup costs are also much higher.

Ans so you're often stuck with python.

We desperately need good math/AI support in faster languages than python but which are easier than c++. c#? Java?

Danmctree··on America underestimates the difficulty of bringing manufacturing back
The toll was far greater than just that of conflicts. If you look at increased mortality during the period you'll see excess death in the millions. Wiki says 3.4 million: https://en.m.wikipedia.org/wiki/Dissolution_of_the_Soviet_Un...

In absolute terms it's one of the harshest death tolls in the last decades. It's far from a joke. Though for completeness, AIDS was also going on there and it's hard to tell from the stats the proportion of impact

Danmctree··on The Decline of the U.S. Machine-Tool Industry and Prospects for Recovery (1994)
Yes the current period is reminiscent of the Mao period in more than one way. You've got blind loyalty and optimism by the followers, unwillingness to listen to critism, anti-intellectualism, attempts to purge aspects of culture and dissappearing disliked people to faraway prisons.

It's not gone nearly as far as in that period, but we ought to be careful not to get closer. When information countering government policy is suppressed, the mistakes keep growing bigger until the consequences become so grave they can no longer be ignored.

Danmctree··on US Administration announces 34% tariffs on China, 20% on EU
The numbers appear to be based on the trade deficit alone, not on any differences in import duties etc.

You would see many more distorted galaxies if this kind of effect would contribute a lot of illusory galaxies
Danmctree··on Object that fell from the skies identified as separation ring from a rocket
There have been a bunch of very powerful non-nuclear explosions. Perhaps a part of an exploding ship such as in the halifax explosion or the Princess Irene?
Danmctree··on The world of tomorrow
By what definition? It's certainly possible that some kind of societal bell curve or other distribution can just keep getting wider without meaningful movement of the relative positions of individuals. I don't understand why you assume the most likely behavior is regression to the mean. Especially on short terms that seems weird to assume
Danmctree··on The Webb Telescope further deepens the Hubble tension controversy in cosmology
Is there a good place to find redshift data and distance estimates for many galaxies?
